<abstract>
<p>This study examined the impact of an 8-week group music game intervention on cooperative behavior in 5- to 6-year-old children. A 2&#x202F;&#x00D7;&#x202F;3 mixed experimental design was employed, with 60 children randomly assigned to either an experimental group (<italic>n</italic>&#x202F;=&#x202F;30) or a control group (<italic>n</italic>&#x202F;=&#x202F;30). The intervention consisted of movement-synchronized rhythm games during the first 4&#x202F;weeks, followed by instrumental ensemble games in the final 4&#x202F;weeks. Cooperative behavior was assessed using the Truck Racing Task before, during, and after the intervention. Repeated-measures ANOVA revealed that: (1) the rhythm game phase significantly improved cooperative behavior; (2) the instrumental ensemble phase produced further additive gains; and (3) intervention effects remained stable after a one-week follow-up, indicating short-term sustainability. These findings demonstrate for the first time that structured group music games can effectively enhance cooperative behavior in naturalistic classroom settings, offering empirical support for the use of music-based interventions in early social development.</p>

<title>Introduction</title>
<p>Cooperation refers to coordinated social interaction among multiple individuals to achieve a common goal (<xref ref-type="bibr" rid="ref17">Hay et al., 2022</xref>; <xref ref-type="bibr" rid="ref42">Tomasello et al., 2005</xref>) and is a core competency in children&#x2019;s social development. The preschool period is a critical stage for the development of cooperative abilities. The cooperative abilities formed during this stage not only lay the foundation for children to establish positive peer relationships but also have a profound impact on their cognitive development and social adaptation (<xref ref-type="bibr" rid="ref39">Tang et al., 2025</xref>; <xref ref-type="bibr" rid="ref49">Yuill et al., 2014</xref>; <xref ref-type="bibr" rid="ref8">Etel and Slaughter, 2019</xref>).</p>
<p>The development of early cooperative behavior exhibits a distinct age-graded pattern. Research indicates that infants can perceive others&#x2019; goals and exhibit a tendency to help as early as their first year of life (<xref ref-type="bibr" rid="ref37">Slocombe and Seed, 2019</xref>), and by 12&#x202F;months of age, they begin to develop coordinated interactions with peers (<xref ref-type="bibr" rid="ref9">Fantasia et al., 2014</xref>; <xref ref-type="bibr" rid="ref19">Kaartinen et al., 2019</xref>). As children grow older, their cooperative behavior evolves from simple dyadic interactions to complex group collaboration (<xref ref-type="bibr" rid="ref11">Fitzgerald and Frankie, 1982</xref>), with significant improvements in the purposefulness and stability of their behavior (<xref ref-type="bibr" rid="ref46">Warneken et al., 2006</xref>; <xref ref-type="bibr" rid="ref16">Gr&#x00E4;fenhain et al., 2013</xref>). This developmental trajectory is shaped by both environmental and individual factors.</p>
<p>Among various influencing factors, interpersonal synchrony has been widely supported as a key mechanism promoting cooperative behavior (<xref ref-type="bibr" rid="ref47">Wiltermuth and Heath, 2009</xref>; <xref ref-type="bibr" rid="ref34">Rennung and G&#x00F6;ritz, 2016</xref>; <xref ref-type="bibr" rid="ref38">Stupacher et al., 2017</xref>; <xref ref-type="bibr" rid="ref3">Cirelli, 2018</xref>; <xref ref-type="bibr" rid="ref5">daSilva and Wood, 2025</xref>; <xref ref-type="bibr" rid="ref41">Tarr et al., 2014</xref>; <xref ref-type="bibr" rid="ref33">Rabinowitch and Meltzoff, 2017</xref>). Interpersonal synchrony refers to the coordinated alignment of behavior across time dimensions among two or more individuals (<xref ref-type="bibr" rid="ref3">Cirelli, 2018</xref>). It encompasses not only motor synchronization of behavioral actions but also temporal synchronization of physiological activities or emotional processes (<xref ref-type="bibr" rid="ref25">Lin et al., 2024</xref>; <xref ref-type="bibr" rid="ref27">Mayo and Gordon, 2020</xref>). Existing research suggests that interpersonal synchrony may enhance joint attention abilities (<xref ref-type="bibr" rid="ref42">Tomasello et al., 2005</xref>), induce positive emotional experiences (<xref ref-type="bibr" rid="ref13">Galbusera et al., 2019</xref>; <xref ref-type="bibr" rid="ref21">Kim, 2025</xref>), reducing psychological distance to enhance prosocial tendencies (<xref ref-type="bibr" rid="ref4">Cirelli et al., 2014</xref>), influencing the brain&#x2019;s reward system (<xref ref-type="bibr" rid="ref45">Wang et al., 2021</xref>), and activating the endogenous opioid system (<xref ref-type="bibr" rid="ref26">Loseth et al., 2014</xref>; <xref ref-type="bibr" rid="ref28">Mogan et al., 2017</xref>) among other pathways, to promote cooperative behavior.</p>
<p>Music activities, due to their inherent rhythmic characteristics, are considered an ideal medium for interpersonal synchronization (<xref ref-type="bibr" rid="ref40">Tarr, 2017</xref>; <xref ref-type="bibr" rid="ref24">Lang et al., 2016</xref>; <xref ref-type="bibr" rid="ref6">Demos et al., 2012</xref>; <xref ref-type="bibr" rid="ref47">Wiltermuth and Heath, 2009</xref>). Group music games are particularly valuable for research due to their rhythmic, interactive, and emotionally evocative characteristics (<xref ref-type="bibr" rid="ref2">Beck and Rieser, 2020</xref>), which can effectively activate the collective intentionality of &#x201C;synchronized vocalization and movement&#x201D; (<xref ref-type="bibr" rid="ref22">Kirschner and Tomasello, 2010</xref>). However, there remains disagreement regarding the impact of musical synchrony on cooperative behavior: supportive evidence suggests that, under laboratory conditions, 4-year-old children exhibit significantly enhanced prosocial intentions following synchronized musical activities (including singing, dancing, and playing musical instruments together) (<xref ref-type="bibr" rid="ref22">Kirschner and Tomasello, 2010</xref>). However, <xref ref-type="bibr" rid="ref1">Baier et al. (2021)</xref> conducted a field experiment in a kindergarten setting and found no significant differences in prosocial behavior between the music condition and the non-music condition, with no effects of gender or age, suggesting that the original results may have been overestimated and emphasizing that differences between laboratory and field experiments may lead to inconsistent results.</p>
<p>The above discrepancies may be due to the following reasons: first, both studies were single-session short-term interventions, which may have led to unstable results. Additionally, the laboratory environment may have amplified the effects of the music intervention, while the real-world environment allowed children to respond more naturally to music activities, thereby weakening the effects. Second, <xref ref-type="bibr" rid="ref22">Kirschner and Tomasello (2010)</xref> incorporated a multi-dimensional collaborative approach to music intervention, including singing, dancing, and instruments, whereas <xref ref-type="bibr" rid="ref1">Baier et al. (2021)</xref> separated these conditions, potentially reducing collaborative effects. Finally, both studies assessed prosocial behavior immediately after a single intervention, without considering the delayed effects or cumulative effects of the intervention.</p>
<p>Based on this, the present study innovatively implemented an 8-week phased group music game intervention program (the first 4&#x202F;weeks focused on rhythm games emphasizing movement synchronization, followed by 4&#x202F;weeks of instrumental ensemble games using musical instruments) to systematically examine the short-term sustained promotional effects of music synchronization activities on cooperative behavior in 5- to 6-year-old children in a kindergarten classroom setting. The study design has the following prominent features: (1) Long-term intervention in a natural educational setting addresses the methodological limitations of previous single-session laboratory studies, which lacked ecological validity, and short-term on-site interventions, which showed insignificant effects; (2) Through a progressive design from rhythmic synchronization to instrumental ensemble, the study verifies the sequential synergistic effects of different types of music synchronization activities on cooperative behavior; (3) A dynamic tracking model of &#x201C;intervention-interval-assessment&#x201D; is adopted, with assessments conducted 1 week after the conclusion of each intervention phase. This approach avoids the practice effects of immediate assessments while also testing the delayed stability of intervention effects.</p>

<title>Aims</title>
<p>This study employed a 2&#x202F;&#x00D7;&#x202F;3 mixed experimental design (Group: experimental/control &#x00D7; Time: T1/T2/T3) to examine the effects of an 8-week, two-phase music intervention on cooperative behavior in 5&#x2013;6-year-olds. The experimental group received 16 sessions (twice weekly), with the first 4&#x202F;weeks focusing on movement-synchronized rhythm games and the latter 4&#x202F;weeks on instrumental ensemble games, while the control group continued regular activities. We hypothesized that:<list list-type="order">
<list-item>
<p>Rhythmic games based on movement synchronization (weeks 1&#x2013;4) would significantly improve cooperative behavior;</p>
</list-item>
<list-item>
<p>Instrumental ensemble games (weeks 5&#x2013;8) would produce additive gains beyond rhythm training;</p>
</list-item>
<list-item>
<p>Intervention effects would remain stable in delayed assessments, with the experimental group outperforming controls.</p>

<title>Participants</title>
<p><italic>A priori</italic> power analysis was conducted using G&#x002A;Power 3.1 (<xref ref-type="bibr" rid="ref10">Faul et al., 2007</xref>) for a 2&#x202F;&#x00D7;&#x202F;3 mixed-design ANOVA (between-factor: group; within-factor: time). With an anticipated large effect size (<italic>f</italic>&#x202F;=&#x202F;0.425, equivalent to Cohen&#x2019;s <italic>d</italic>&#x202F;=&#x202F;0.85 based on prior music intervention studies), &#x03B1;&#x202F;=&#x202F;0.05 (two-tailed), power&#x202F;=&#x202F;0.85, and an assumed repeated-measures correlation of <italic>&#x03C1;</italic>&#x202F;=&#x202F;0.5, the analysis indicated a minimum requirement of 26 participants per group. To accommodate potential attrition and enhance statistical robustness, we recruited 60 typically developing children (27 boys, 33 girls; mean age&#x202F;=&#x202F;5.6&#x202F;&#x00B1;&#x202F;0.3&#x202F;years) from kindergarten senior classes, with 30 participants randomly assigned to each group. The experimental group comprised 16 girls and 14 boys, while the control group consisted of 17 girls and 13 boys.</p>
<p>Inclusion criteria were: (1) Middle socioeconomic status (SES) families; (2) No prior participation in structured prosocial or music-based interventions; (3) No developmental disabilities or cognitive impairments (verified through kindergarten health records).</p>
<p>Randomization was performed by an independent researcher using computer-generated random numbers (block randomization with a 1:1 allocation ratio), with balanced gender ratios (experimental: control&#x202F;=&#x202F;7:8).</p>

<title>Ethical review</title>
<p>All studies involving participants were conducted with the consent of teachers and parents. The research content and process were approved by the ethics committee of the authors&#x2019; university, and the parents of the research participants all signed informed consent forms.</p>

<sec id="sec7">
<title>Research phases</title>
<p>This study was divided into a pre-experimental phase and a formal experimental phase. Two weeks before the formal experiment, six boys and six girls were selected for the pre-experiment to validate the appropriateness of the intervention program. Subsequently, the formal experimental phase began, with the experimental group of preschoolers undergoing an eight-week group music game intervention. The first 4 weeks focused on rhythmic music games emphasizing movement synchronization, while the final 4 weeks involved more complex instrumental ensemble game interventions. One week before the formal experiment began, pre-tests of cooperative skills were conducted for both the experimental and control groups. To avoid practice effects, mid-tests and post-tests were conducted 1 week after the intervention, specifically the mid-test of cooperative skills was conducted before the fifth week of intervention, and the post-test was conducted in the ninth week.</p>
<p>During the 8-week intervention period, the control group continued their regular kindergarten curriculum (including free play, arts, and storytime activities) without any structured music-based cooperation training.</p>

<title>Group music games</title>
<p>The intervention consists of 16 group music game activities, with the first 8 activities focusing on rhythmic games emphasizing movement synchronization, and the latter 8 activities involving more complex instrumental ensemble games.</p>
<p>The intervention program was developed through collaborative discussions among university faculty members specializing in early childhood music education, graduate students, and kindergarten teachers. Feedback was solicited via email from 3 university faculty members and 5 kindergarten teachers specializing in early childhood education, and the program content was revised based on their written suggestions. Additionally, a pre-experiment was conducted with 12 randomly selected non-experimental group preschoolers in kindergarten prior to the intervention, focusing on observing children&#x2019;s understanding of cooperative tasks, such as their ability to independently negotiate instrument allocation, the appeal of musical materials, and the effectiveness of cooperative behavior triggers. The intervention plan was adjusted based on the pre-experiment results and finalized (specific plan excerpts are shown in <xref ref-type="table" rid="tab1">Table 1</xref>).</p>

<p>This study conducted interventions in the form of group music games in the classroom activity room, with each session lasting 25&#x2013;30&#x202F;min, twice a week, for a total of 16 sessions over 8 weeks. Each activity was divided into four stages, with the specific process as follows:<list list-type="order">
<list-item>
<p>Contextual Introduction: Through the creation of a story-based scenario, a &#x201C;cooperation gap&#x201D; is established to foster a group atmosphere. The core task of &#x201C;collaborative activation&#x201D; is anchored to stimulate children&#x2019;s interest in participation, establishing a connection between &#x201C;individual participation&#x201D; and &#x201C;collective goals&#x201D; to drive the generation of cooperative intentions, ensuring children understand the need to work together.</p>
</list-item>
<list-item>
<p>Imitation Experience: Teachers guide children to actively participate in music games, using skill imitation through body movement and instrument operation to simultaneously instill &#x201C;follow-instructions collaboration&#x201D; and &#x201C;spatial coordination&#x201D; rules. This process combines &#x201C;motor skill acquisition + social rule internalization&#x201D; to help children understand &#x201C;how to do it.&#x201D;</p>
</list-item>
<list-item>
<p>Group Collaboration: Using &#x201C;rhythm task division&#x201D; as a medium, children voluntarily or randomly form different groups, each assigned specific tasks (such as actions or instrument playing with different rhythms), to directly experience the essence of collaboration where &#x201C;tasks differ but goals are aligned,&#x201D; enabling children to &#x201C;do their part well.&#x201D;</p>
</list-item>
<list-item>
<p>Comprehensive application: Through synchronized demonstrations of movements with different rhythms and collaborative performances of various instruments with different rhythms, while occasionally introducing small challenges (such as &#x201C;suddenly increasing the music speed&#x201D; or &#x201C;adding a new movement&#x201D;), children experience the process of &#x201C;individual or group efforts&#x201D; converging into &#x201C;collective achievements,&#x201D; feeling the sense of accomplishment that &#x201C;collective effort is more powerful than individual action,&#x201D; and learning to &#x201C;adjust for a common goal.&#x201D;</p>

<title>Truck racing task</title>
<p>We assessed cooperative behavior using the validated Truck Racing Task (<xref ref-type="bibr" rid="ref7">Deutsch, 1973</xref>), which has demonstrated reliability in preschool studies (<xref ref-type="bibr" rid="ref29">Nalis et al., 2018</xref>; <xref ref-type="bibr" rid="ref36">Shomer et al., 1966</xref>). To ensure scoring objectivity, two trained early childhood education graduate students independently rated all cooperative behavior assessments, and the raters were blind to the children&#x2019;s group assignments, which significantly strengthens the internal validity. Raters completed standardized training comprising: (1) a detailed review of scoring protocols, (2) consensus calibration through video analysis, and (3) practice coding achieving excellent reliability (<italic>&#x03BA;</italic>&#x202F;&#x003E;&#x202F;0.85). Final inter-rater reliability remained high (<italic>&#x03BA;</italic>&#x202F;=&#x202F;0.92), with discrepancies resolved through joint review by the first author and corresponding author. Periodic reliability checks (10% random resampling) confirmed ongoing scoring consistency (<italic>&#x03BA;</italic>&#x202F;&#x003E;&#x202F;0.90 throughout data collection).</p>
<p>The measurement tool is used as follows: Children participate in pairs, each driving Truck A or Truck B, following a route map (as shown in <xref ref-type="fig" rid="fig1">Figure 1</xref>). Each truck is required to depart from the starting point and reach the destination as quickly as possible (time is not actually measured; only the children&#x2019;s path selection is observed). Each truck has its own dedicated route, but this route is long and time-consuming. A one-way road is set up in the middle, which both parties can use but only one truck at a time. This one-way road is short, and the waiting time increased by alternating use of the one-way road is more economical and efficient than using the backup route. Communication between the two parties is allowed during the experiment. Finally, the level of cooperative behavior is scored based on the routes chosen by the two children.</p>

<title>Discussion</title>
<p>This study systematically examined the effects of action synchronization and instrumental ensemble playing on cooperative behavior in 5- to 6-year-old children through an 8-week phased group music game intervention. The main findings can be summarized in three aspects: (1) The action rhythm games in the first 4&#x202F;weeks significantly improved cooperative behavior; (2) The instrumental ensemble games in the latter 4&#x202F;weeks further reinforced the effects; (3) The intervention effects demonstrated temporal stability over short-term intervals, remaining significant in assessments conducted 1 week after each intervention phase. These results not only validate the theoretical hypothesis that musical synchrony promotes prosocial behavior (<xref ref-type="bibr" rid="ref22">Kirschner and Tomasello, 2010</xref>) but also, through a phased design, provide the first empirical evidence of the sequential facilitation effect of motor synchronization and instrumental ensemble activities on cooperative behavior. This finding provides a new empirical perspective for understanding the relationship between musical activities and the development of prosocial behavior.</p>
<p>First, the phased intervention design aligns with developmental patterns. This study employed a two-phase intervention protocol progressing from motor synchronization to instrumental ensemble activities, reflecting the developmental trajectory of cooperative abilities from embodied interaction to symbolic collaboration. The first 4 weeks of the action synchronization phase involved rhythmic physical activities such as clapping and stepping, consistent with the cognitive development characteristic of &#x201C;action preceding thought&#x201D; in young children (<xref ref-type="bibr" rid="ref32">Piaget, 1952</xref>). In the subsequent 4 weeks of the instrumental ensemble phase, children were required to translate rhythmic symbols into concrete actions, such as using percussion instruments to represent strong beats and string instruments to represent weak beats. This precise correspondence between symbols and actions helps promote the development of logical thinking. Additionally, real-time monitoring and adjustment of one&#x2019;s own and peers&#x2019; performances during ensemble playing helps overcome egocentrism (<xref ref-type="bibr" rid="ref44">Wan and Zhu, 2021</xref>). The research findings also align with Parten&#x2019;s stages of play development theory (<xref ref-type="bibr" rid="ref30">Parten, 1932</xref>), progressing from parallel play in the motor synchronization stage to cooperative play in the instrumental ensemble stage.</p>
<p>Second, gamified design stimulates children&#x2019;s intrinsic motivation for cooperation (<xref ref-type="bibr" rid="ref31">Perez-Aranda et al., 2023</xref>; <xref ref-type="bibr" rid="ref14">Goagoses et al., 2023</xref>). The unique pleasure, interactivity, and immediacy of group music games effectively stimulate children&#x2019;s motivation to cooperate. First, the pleasurable experience of music games provides an emotional driving force for cooperative behavior (<xref ref-type="bibr" rid="ref48">Wu and Lu, 2021</xref>). Second, the interactive process enhances liking and trust among peers, reinforcing collective identity (<xref ref-type="bibr" rid="ref20">Kara and Taner Derman, 2025</xref>; <xref ref-type="bibr" rid="ref15">Good et al., 2017</xref>; <xref ref-type="bibr" rid="ref3">Cirelli, 2018</xref>). Finally, the immediate feedback from the collaborative effect (e.g., rhythmic consistency) forms positive reinforcement, which may regulate prosocial behavior by influencing the neural activity of key brain regions in the reward system (nucleus accumbens, medial prefrontal cortex) (<xref ref-type="bibr" rid="ref43">Walsh et al., 2023</xref>; <xref ref-type="bibr" rid="ref45">Wang et al., 2021</xref>), prompting children to actively adjust their behavior to cooperate with others.</p>
<p>Third, structured process systems promote cooperative behavior. The intervention employs a four-step fixed process: Contextual introduction uses anthropomorphic stories to transform abstract cooperative tasks into concrete &#x201C;helping&#x201D; behaviors, stimulating children&#x2019;s prosocial instincts and facilitating the formation of collective intent and joint attention (<xref ref-type="bibr" rid="ref8">Etel and Slaughter, 2019</xref>); Imitation experiences ensure that all participants master basic skills, preventing cooperation withdrawal due to ability differences, while implicitly conveying cooperation rules through repeated practice, achieving the internalization of cooperation rules (<xref ref-type="bibr" rid="ref2">Beck and Rieser, 2020</xref>); Group collaboration cultivates critical role awareness and perspective-taking abilities through role division and negotiation (<xref ref-type="bibr" rid="ref12">Flavell et al., 1981</xref>); Comprehensive application promotes children&#x2019;s development from mechanical coordination to flexible collaboration through integrated demonstrations and dynamic challenges. The above process aligns with children&#x2019;s cognitive characteristics, progressively enhancing their cooperative abilities through motivation, skill-building, and practice reinforcement.</p>
<p>Fourth, neural mechanisms support the effectiveness of staged interventions. The intervention effects in this study may stem from neural-behavioral coupling triggered at different stages: the action synchronization stage primarily activates the mirror neuron system (<xref ref-type="bibr" rid="ref35">Rizzolatti et al., 2001</xref>) and enhances interbrain synchronization (<xref ref-type="bibr" rid="ref4">Cirelli et al., 2014</xref>), promoting joint attention and action empathy; while the instrumental ensemble stage significantly activates the prefrontal executive function network (<xref ref-type="bibr" rid="ref18">Hyde et al., 2009</xref>), reinforcing social cognitive abilities such as rule adherence and intent understanding. This progressive activation from the sensorimotor network to the social brain network is consistent with (<xref ref-type="bibr" rid="ref23">Kokal et al., 2011</xref>) multi-level model of interpersonal synchronization, explaining why the two-stage intervention produces sequential facilitation effects.</p>
<p>In summary, this study, by constructing a &#x201C;bodily rhythm -instrumental ensemble&#x201D; staged intervention model, empirically demonstrated for the first time in a natural educational setting the sequential facilitation effect of music synchronization training on cooperative behavior in 5- to 6-year-old children, resolving previous discrepancies regarding the effects of single music interventions and providing new perspectives for music intervention theory and practice.</p>
<p>Despite these important findings, the study has the following limitations: limited cultural diversity of the sample; lack of long-term follow-up data; the regular curriculum activities in which the control group participated did not involve structured cooperation comparable to that of the intervention group; and absence of neurophysiological measurement techniques. Future research is recommended to: (1) use an active control group (e.g., non-musical cooperative games); (2) explore potential mediator or moderator variables (e.g., children&#x2019;s personality traits or family environment); (3) conduct cross-cultural comparisons; (4) extend follow-up periods; (5) refine age-differentiated studies; and (6) employ fNIRS or similar technologies to provide physiological evidence. These improvements will help further validate the promotional effects of group music games on cooperative behavior.</p>
